Typhoid fever is caused by the bacterium Salmonella enterica serotype Typhi. The primary causes of typhoid fever include:
-
Contaminated Food and Water: The most common route of transmission is ingestion of food or water contaminated with the bacteria. This often occurs in areas with poor sanitation and hygiene practices.
-
Poor Sanitation: Lack of proper sewage disposal and access to clean drinking water increases the risk of typhoid transmission.
-
Carrier States: Individuals who are asymptomatic carriers of the bacteria can spread the infection through food or water. These carriers can shed the bacteria for long periods, even if they do not show symptoms of the disease.
-
Close Contact: Living in close quarters with infected individuals can facilitate the spread of the bacteria.
Preventative measures include improving sanitation, ensuring clean drinking water, and practicing good personal hygiene.
